The building of Crimea's government was taken over by a group of some 30 people at around 0430 local time on Thursday, the Crimean prime minister's spokesperson Violetta Lisina told Interfax-Ukraine.

These persons ordered police officers guarding the government headquarters to leave the building and gave their officially issued weapons and ID cards back to them, she said.

An official who was on duty at the prime minister's reception office was allowed to leave the building as well.

"No one was injured during the events," Lisina said.

The spokesperson also announced Crimean Prime Minister Anatoliy Mohyliov's upcoming televised address.
